Bulgaria generated 34.46 TWh of electricity between 1 January and 4 October, up 12.24% year on year. The increase coincided with higher renewable output and lower generation from coal and nuclear sources. Electricity consumption rose 8.45% to 30.96 TWh. Net exports were approximately 3.5 TWh.
Coal and nuclear output declines as total generation rises
Combined coal and nuclear production fell 3.1% to 21.25 TWh. With coal and nuclear lower, the rise in overall generation came from other sources. The data indicate Bulgaria maintained an export surplus even as domestic demand increased. Renewables accounted for a larger share of meeting consumption.
Renewables increase on transmission and distribution networks
Renewable generation connected to the transmission network increased 27.89% to 4.12 TWh. Renewable output on distribution networks rose 10.97% to 3.62 TWh. Together, the figures show growth across both grid connection levels during the period measured. The annual balance does not specify when the export surplus was available.
Timing of renewable output affects market value
The timing of production is relevant for how additional renewables translate into system conditions. Solar-led growth can increase daytime supply while leaving evening demand more dependent on dispatchable generation, imports or storage. For traders and investors, the key question is how output changes affect hourly prices and export availability. Rising annual generation supports Bulgaria’s regional supply role, but commercial value depends on when electricity is produced.
